The Ultraviolet Imaging Telescope
UIT was one of three ultraviolet telescopes on the ASTRO-1 mission
flown on the space shuttle Columbia during 2-10 December 1990.
The same three instruments were later flown on the space
shuttle Endeavour from 3-17 March 1995, as part of the ASTRO-2 mission.
Exposures were obtained on 70-mm photographic film
in the 1200-3300 Å range using broadband filters and later
digitized using a Perkin-Elmer microdensitometer. Image resolution
was 3" over a 40' field of view.
Overall, UIT-1 obtained 821 exposures of 66 targets, and UIT-2
obtained 758 images of 193 targets.
